title: Navifocus WR is the promising intravascular ultrasound for navigating the guidewire into true lumen during the coronary intervention for chronic total occlusion.
abstract: We describe an initial clinical chronic total occlusion (CTO) case in which CTO-specific intravascular ultrasound (IVUS): Navifocus WR was useful for navigating the second guidewire into the true lumen under the IVUS observation from the subintimal space.
